Dates for their return to court have been separated, with the Comancheros to return to court on December 19 and the Hells Angels the following day.

Earlier Hells Angels member Dennis Basic, 33, appeared in court to face 13 charges, including seven counts of possessing fire arms, including a semi automatic rifle, a sawn off pump action shot gun and one count of possessing a silencer.

Other charges relate to storing and making bomb-making materials, including detonators and explosive gels.

His lawyer told the court he is charged with possessing "minute quantities" of drugs and it is not alleged he is involved in other activities.

He was released from custody under orders not to associate with members of the Hells Angels Seaford chapter, other than his brother and not go near the clubhouses.

Two other gang members also appeared in court.

Neke Wirihana, 21 from Mornington, a member of the Hells Angels, appeared in the Melbourne Magistrates Court and was remanded.

Comanchero Bashkim Gashi, 30, of Dandenong North, appeared in the Dandenong Court and was also remanded in custody.

More than 180 police raided and searched 10 properties connected with outlaw motorcycle gangs including one Comancheros club room and one club room of the Hells Angels.

It is alleged the Hells Angels members were involved in two recent shootings at Comancheros' properties.

In yesterday's Melbourne raids, police seized a total of 10 firearms and explosives, as well as cash and drugs.

Police allege all but one of the five Comancheros are involved in an extortion racket - using violent standover tactics to collect debts.

After yesterday's raids, acting assistant commissioner Tess Walsh said police are investigating if any of the weapons seized in the raids are connected to a series of shootings between the rival groups in recent days.

"The examination should reveal whether or not any of these have been used in any of these crimes," she said.

She says the raids were the result of months of investigations, under the guise of the Echo Taskforce.

"Certainly the activities of the last few days have been very concerning to us and perhaps prompted some of our response... but the majority of the charges are the result of investigations that we've had continuing for quite some time," she said.

"A number of them have been the subject of attacks over recent months here in Victoria and I'm sure in other jurisdictions as well," he said.

"There is illegal activity taking place. We should be using every means possible to make it a hostile environment for their activities."

Under new laws - which the Queensland Government says are the world's toughest - gang members will be banned from gathering in groups, wearing club colours in bars and restaurants, and owning or working in a tattoo parlour.
